oh yeah... BTW... customer service is DEFINETLY something to be concerned with if you aren't to up on how these systems work. They can be very complex at first till you get some base specs in that are decent. I Have alwasy been very happy with Holley's srvice and I talk numerous times a year with their reps. I have also talked with a represenative from FAST and they are helpful as well. Although ideally if you are scared, go for an Accel system. The Calmap software is pretty easy to use and there are a ton of peolpel out on the net that have these systems, have base specs you can downlaod and different manuals. I would bet there is a mailing list out there somewhere as well.
